This invention relates topads to be used in connection with mattresses.

It is a well known fact that it costs practically as much to have asagged mattress reconditioned as a new mattress of equal quality wouldcost, but by use of a compensating pad a sagged and uncomfortablemattress can be rendered practically a new one at a very small cost.

One of the objects of the invention is to provide, in a manner ashereinafter set forth, a compensating pad to bcplaced above or "below amattress which has lost its resiliency and the stuffing thereincompressed by-the weight of the person.

Another object of the invention is to provide, in a manner ashereinafter set forth, a

compensating pad which may be used either' on top of the mattressbetween the mattress and the covering sheet or under the mattressbetween the mattress and the springs where the springs have lost theirresiliency or become permanently sagged through use.

Further objects of the invention are to provide in a manner ashereinafter set forth, a device for the purpose referred to, which isnot only indispensible within the house hold but very valuable inhotels, and especially hospitals where the sick are required to lie forprolonged periods of time, destroying the resiliency of the mattress,and which is simple in its construction and arrangement, thoroughlyefficient for its intended use, soft,

liable and comfortable when in position,

5 convenient and light to handle, without interfering with the efficientdaily dressing of the bed and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists ofanovel construction, combination and arrangement of parts, ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shownan embodiment of the invention,but it is to be understood that changes, variations and modificationsmay be resorted'to which fall within the scope of the claimshereunto-appended.

v In the drawings wherein like reference characters. throughout theseveral view-s:-

as good as j side elevation.

denote corresponding parts Figure 1 shows a side elevation of a bedspring, with a longitudinal sectional view of a mattress superimposedupon a compensating pad illustrating in longitudinal section al-adaptation therewith of the compensating pad in accordance with thisinvention.

Figure 2 is a top plan view in upright position of'the compensating padin accordance with this invention.

Figure 3 is a longitudinal'section of the mattress having superimposedthereon in inverted position a compensating pad shown in Figure 4 is anend elevation of the compensating pad in upright position.

Figure 5 is an end elevation of a modified form of the invention. FReferring to Figure 1 of the drawings, 5 designates a conventional typebed spring having-acompensatin pad in accordance with this inventionindicated generally at 6, resting in upright position on the springs andhaving the original mattress 7 superimposed on the compensating pad 6.

The compensating pad 6 is generallyof rectangular contour of a lengthgreater than its width. Its rectangular dimensions conform to theoriginal mattress with which it is to be used and therefore may,vary-according to the size of the standard mattress on which it is tobe used, such as full size, threequarter size, orv cot size. The body ofthe compensating pad is flexible and consists of a shell or casingcomposed of a one-piece up-' per member Sand a one-piece lower member 8formed of ticking or other strong, pliable fabric which encloses andconfines the stuffing or wadding 9. Theuppe'r and lower cas- 9O ingmembers are secured together at their marginal edges by a row ofstitching 8". The waddingor stuiiin g may be formed of any elasticmaterial such as cotton, wool, felt or hair.

The entire upper surface of the compensating pad, when in the uprightposition shown in Figures 1,2 and 4, is provided with spaced polygonalblocks of tufting formed by a plurality of spaced raised polygonalportions 10. The spaced raised portions are bound at their margins byvalleys 11, forming a plurality of polygonal shaped interconnectingvalleys over the tog surface of the pads. The valleys are forme as aresult of stitching 11 extending transversely through stufiing 9 andfrom the upper to the lower members 8, 8. The stitching prevents thestufiing 9 from shifting because it is slightly compressed along theline of stitching and moreover because it is anchored thereby to theupper and lower members 8, 8. The polygonal tufting formed by the raisedportion 10 bound by the valleys 11 form irregular surfaces on the top ofthe compensating pad making the compensating pad soft and cushion-likeand preventing the stuffing from shifting.

The bottom of the compensating pad indicated generally at 12 and when inthe upright position is'flat and of rectangular contour. The top of thepad indicated generally at 13, is of rectangular marginal contour. Thetop face of the pad, in addition to the tufting inclines upwardly fromthe marginal edges 14, 15, 16 and 1 7 to a central substantiallyrectangular area 18, and the thickness of the pad increases inproportion to the inclination. The marginal edges 14,15, 16 and l'Z arenot of feather or knife edge thickness but are thick enough to provide asubstantial body to the pad along its edges. The marginal edges of thepad are however, of a material less thickness than that portion thereofat the'center 18. x

In the modified form of the invention shown in Figure 5 of the drawings,instead of having a fiat bottom 12 as in the preferred form, the saidbottom is made complementary with the top. To be more specific,beginning at the marginal edges of the pad 14, 15 and 17 and the otheredge obscured from view in Figure 5, the upper surface is indicatedgenerally at 13 and the lower surface indicated generally at 12 inclineinwardly from the marginal edges to a central substantially rectangulararea 18 on the top and 18" on the bottom. Both the .top surface 13 andthe bottom surface'12 are quilted the same as the preferred form of theinvention and the shell or casing is made up of a one-piece top memberand a one-piece bottom member ettlivalent to 8 and 8' in the preferredform w ich are secured together at their marginal edges by a row ofstitching. The modified form of the invention will compensate for asagging spring as well as a cupped mattress by reason of itscomplementary sloping upper and lower surfaces.

In the application of the preferred form of this invention thecompensating pad may be used in its upright position, as shown inFigures 1, 2 or 4 or in the inverted position shown in Figure 3. In thelatter application the top face 13 is placed against the top of the ingpad will therefore fall under, or be placed over the point where thegreatest cupping will occur in the mattress, and by reason thereof willcompensate for the sagging or cupping by filling in the cavity formedthereby. Since the compensating pad diminishes in thickness toward themarginal edges, the cavity or cup will be filledwithout effecting thelevel surface of themattress. The result of the invention, will providea flat level surface for a person to rest on, without the trouble andexpense of buying new bed springs or having the old mattress restufl'edwhen the stufiing therein becomes permanently compressed from use. WhatI claim is 1. A compensating pad for mattresses comprising a flexiblebody corresponding in length and width to that of the mattress, saidbody being formed centrally thereof with a substantially rectangularportion of greater thickness than the remaining portion, said bodygraduall increasing in thickness from each of its-e ges towards saidrectangular portion.

2. A compensating pad for mattresses comprising a flexible bodycorresponding in length and width to that of the mattress, said bodybeing formed centrally thereof with a substantially rectangular portionof greater thickness than the remaining portion, said body graduallyincreasing in thickness from each of its edges towards said rectangularportion, said body having its bottom flat throughout.
